Abstract

The invention concerns an optical electrowetting device a body comprising at least a first external surface and a second internal surface with a conical shape; a liquid-liquid interface between a first and a second immiscible liquids, the first liquid being a conducting liquid and the second liquid being an insulating liquid, wherein the liquid-liquid interface is able to move on the second internal surface by electrowetting effect; a first electrode in contact with the first liquid; a second electrode insulated from the first liquid by an insulating layer, the second electrode comprising at least a first electrical conductive track to be connected to a voltage source and extending from the first external surface of the body to the second internal surface; and a first layer covering the second internal surface of said body and being covered by the insulating layer, wherein the shape of the liquid-liquid interface is controllable by application of at least a first voltage between the first electrode and the first electrical conductive track, and wherein at least one of the body or the first layer is made of a resistive material.
